in Jeffrey Street adjoining the church owned by Dr Cox was rented for £225 and a few years later purchased for £4,500. St Aloysius' College officially commenced classes in Kirribilli on 2 February 1903, with less than 50 students. Before long enrolments again increased and additional accommodation became an urgent need. A wooden building was hastily erected, housing classrooms and study hall until it was replaced in 1907-1908 by a three-storeyed brick building later known as the "Junior School". As student numbers increased, additional rooms again became necessary and in 1913-1914 a new wing was constructed on the eastern side of the original residence. The site has been continually developed since, with significant redevelopment occurring in 1961 and most recently over the period 1979–81. The new building at the northern end of Jeffrey Street will be named Dalton Hall after the Founding Father of St Aloysius' College, Fr Joseph Dalton SJ. It consists of a swimming pool, basketball court, classrooms and offices.

There are carved bargeboards, finials and a lancet ventillator to the gable ends, three-light square-headed windows and iron lace, columns and balustrades to the verandahs." And as being "Built 1876 for Henry Hocken Bligh (1826-1904), former Mayor of Willoughby (1869–70) and husband of Elizabeth Shairp, granddaughter of James Milson. The Blighs lived at No. 16 and owned other properties in the area. It was sold in 1911, through various ownerships until acquired by the Council in 1974. It was restored subsequently as the Kirribilli Neighbourhood Centre."

The centre provides spaces for community activities and parties or celebrations.
